Beast Machines: Transformers (U.S. TV)

Nightscream was originally intended to be a female, but was changed to male at the behalf of the producers.

Saban entertainment, who co-owned FoxKids at the time, created a special promotional music video for the series called "Evolution Revolution". It aired only once on the Network, and featured a clip of a frozen-in-time Cheetor, where the camera circled around him. The clip was never featured in any episode.

The show was developed with both Full Frame and High Definition Widescreen aspect ratios.

This is the only Transformers cartoon to take place entirely on their home planet of Cybertron, excluding a couple of flashbacks of Earth.

The writers were told by the producers not to watch or read any other Transformers-related media, so that they can build up the show from scratch. However they eventually disobeyed them, and started adding concepts seen in previous cartoons, tying the show strongly into the Transformers mythos.

Silverbolt's new form was originally going to be a four-legged griffin.

Writer Robert N. Skir described the show as a "religious epic novel for television".

Only two episodes have sunlight. Most of the events take place at night.

When Fox Kids first put out an early description for the show as a part of its sneak-peek at 1999's fall programming, it featured a wholly different take on the basic cartoon outline, as well as some unfinished character designs. The description promised a story-telling very similar to that of its prequel, Beast Wars: Transformers, with the two opposing factions being the Maximals and Predacons. The completed show differed quite a bit from this: for one, the Maximals faced off against Vehicons, and the ever-present humor of its predecessor was almost completely absent.

Famed Transformers fiction writer Simon Furman considered the series to be too dark for children.

Like most of the Beast Wars voice actors who returned for the sequel Beast Machines, Chalk strongly disliked how his character, Optimus Primal, was rewritten as a religious fanatic and, according to co-star Scott McNeil, would often flip out in anger between recording sessions.
